im looking for a throttle body style aftermarket efi system for my 67 mustang with a 351 and a t5. Does anyone have any opinions, recommendations or experiences. below is the link to the one i'm thinking of getting. i'm wanting to go with a bolt on throttle body because i have a polished intake and want to keep it. I'm going to use a hei style distributor I think.

I don't believe you don't have a chevy tbi or twenty laying around somewhere.
What travis said is the most economical. Atomic msd Efi is pretty cool, Robbie has that.
i guess i should have specified best value for modern self learning. old chevy tbi is ok but its worth the extra couple hundred for a brand new modern self learning system.
and yes i have two boxes full of chevy tbi parts
Roadkill used MSD atomic efi on a build that looked pretty simple. If you're going for a pretty stock motor, I don't really think you can go wrong with any of the aftermarket kits.
motor is 351w with gt40p heads and undecided but healthy cam. so less than 400 hp, the more i read the more i like that kit i posted the link to.
Gt40p heads are ancient, why no aluminum heads? 400 hp is a lofty number when talking about stock ford cast iron heads. I have JBs 69 351 heads machined for screw in rocker studs and full roller rockers from his bronco, and a t5 for sale.
Saw them use FiTech GO EFI on one of the Powerblock shows. It looks intriguing as all the sensors besides the O2 are self contained within the throttle body. Easy and clean install and the system is only around $1k.

ran across this one. it includes a digital monitor that can display all the needed guages it seems. any thoughts?
I currently have a custom aluminum dash all the way across that is solid and un cut yet. I think it would look cleaner to have one digital guage over a bunch of traditional gauges. i'm still tossing around ideas.
Durability of the gauge may be a concern on a topless trail rig but it otherwise looks legit.
Idk what custom aluminum dash means, but the screen isn't very aesthetically pleasing. If you don't mind the screen and you know what you can do for a speedo (didn't read to see if you can integrate something into that screen) then I'd say go with it.

this is for a 67 mustang wish it was a convertible
gt40 heads i can get stock on an explorer along with all the serpentine front dress radiator and condensor along with aluminum driveshaft(which is the correct size for the mustang with a t5 conversion) and disc brake limited slip rear end. pretty solid setup since my mustang has a mustang 2 front suspension already and i can use the low location of the ac compressor due to no shock towers. gt40 heads are the best cast iron head ford ever made for a sb. i can get a whole explorer for 500 and aluminum bare heads would be well over double that then add valves etc etc. im not looking for the fastest mustang. just a quick one that won't break the bank to build.
I bet you are going to be very underwhelmed with the GT-40, especially if you don't do any serious work to them. If you are throwing all of this on a used motor I bet you can barley get 280 HP with that fuel injection. Maybe 300 out of a properly tuned carb on the top end (I recommend fuel injection for drive-ability but have yet to see the budget kits ever make more HP than a good carb).
My suggestion is to do the build with the gt-40 heads and fuel injection from a fox body, then build the rest of the car to handle 450 hp. Once the suspension and drive train is complete swap in a s-trim.
Forget money, gt40 heads are a waste of time. Are you really going to slap some junk yard heads on there with no work because they were cheap? You know al heads come with valves ready to bolt on right?
Nvm, saw the dash. Disregard previous questions.
You don't want to spend money on aluminum heads, which have tons of benefits over cast iron, but you're going to spend 1k on aftermarket efi so it might start a little easier, and might drive a little nicer, even though you're using stock ford heads which I think someone somewhere already made like millions of computers with the right tune on them? Am I understanding that right?
i have a polished intake and matching valve covers that look really good and i want to keep the nostalgic look of the engine bay as much as possible. if i were to use a factory efi system that wouldn't work. hence the all inclusive aftermarket efi with the computer built into the tb that looks like a computer and the normal person would overlook.
i also didn't say no work would be done. gonna have a valve job done and the deck checked and do some port matching myself if i feel like it. as far as investment i don't see it worth it to spend 1500-2500 for a pair of heads. the cheap aluminum will have cheap valves and need a valve job out of the box anyway and i don't see the benefit to spending a ton on a good set of heads for my plans for the car. and saying gt40 heads are junk is like saying vortec heads are junk. yes aftermarket aluminum would be better but i'm in the middle of building several cars so would rather spend the money other places.
that being said if you find a set of aluminum heads for a few hundred bucks ill buy them
the motor im using is a 0 mile 69 351 shortblock i have, came with a set of jacked up cheap aluminum heads that were used and need welding and much more... got quoted 1k to fix them. not worth it. if the were not a chinese knockoff cheap head maybe but they are junk. all i currently have is a shortblock. hence needing the front dress etc from an explorer. if i get anywhere close to 350 i will be happy. in a few years if i still have the car i will probably want to put a coyote motor in it anyway so another reason not to put too much money into the 351 that would end up on a pallet in the back of the warehouse.

i agree for power and bang for the buck ls is the answer. i do like the idea of a mustang motor in a mustang. that would be round 2 of the build either way. for now just get it together and running.
I noticed I put "Barley"
Good luck getting anywhere close to 350hp with the gt40 heads, to do this you better plan on a giant cam, lots of compression and spinning up right to the point where everything wants to fly apart (and it probably will). Also you will lose all of and more of the drive-ability that fuel injection offers.
If money is an issue and you want to keep the "nostalgic look" go with a carb and use the other $400 to build a decent looking dash.
I'm with travis, efi needs to go, and just put a carb on it. Spend the money on heads instead. I have a set of twisted wedge heads NIB with 170cc intake runners, assembled with screw in rocker studs and a set of roller rockers I'll sell you for the 1k that your efi would cost.
I would replace all of it with an LS and T56. :D
Fuel injection AND power. :flipoff2:
Just noticed this. :DQuote:
